I stopped just in time to prevent myself emerging upon an open space. It was a kind of glade in the forest, made by a fall; seedlings were already starting up to struggle for the vacant space; and beyond, the dense growth of stems and twining vines and splashes of fungus and flowers closed in again. Before me, squatting together upon the fungoid ruins of a huge fallen tree and still unaware of my approach, were three grotesque human figures. One was evidently a female; the other two were men. They were naked, save for swathings of scarlet cloth about the middle; and their skins were of a dull pinkish-drab colour, such as I had seen in no savages before. They had fat, heavy, chinless faces, retreating foreheads, and a scant bristly hair upon their heads. I never saw such bestial-looking creatures.

They were talking, or at least one of the men was talking to the other two, and all three had been too closely interested to heed the rustling of my approach. They swayed their heads and shoulders from side to side. The speaker’s words came thick and sloppy, and though I could hear them distinctly I could not distinguish what he said. He seemed to me to be reciting some complicated gibberish. Presently his articulation became shriller, and spreading his hands he rose to his feet. At that the others began to gibber in unison, also rising to their feet, spreading their hands and swaying their bodies in rhythm with their chant. I noticed then the abnormal shortness of their legs, legs and their lank, clumsy feet. All three began slowly to circle round, raising and stamping their feet and waving their arms; a kind of tune crept into their rhythmic recitation, and a refrain, — “Aloola,” or “Balloola,” it sounded like. Their eyes began to sparkle, and their ugly faces to brighten, with an expression of strange pleasure. Saliva dripped from their lipless mouths.

Suddenly, as I watched their grotesque and unaccountable gestures, I perceived clearly for the first time what it was that had offended me, what had given me the two inconsistent and conflicting impressions of utter strangeness and yet of the strangest familiarity. The three creatures engaged in this mysterious rite were human in shape, and yet human beings with the strangest air about them of some familiar animal. Each of these creatures, despite its human form, its rag of clothing, and the rough humanity of its bodily form, had woven into it — into its movements, into the expression of its countenance, into its whole presence — some now irresistible suggestion of a hog, a swinish taint, the unmistakable mark of the beast.

I stood overcome by this amazing realisation and then the most horrible questionings came rushing into my mind. They began leaping in the air, first one and then the other, whooping and grunting. Then one slipped, and for a moment was on all-fours, — to recover, indeed, forthwith. But that transitory gleam of the true animalism of these monsters was enough.

I turned as noiselessly as possible, and becoming every now and then rigid with the fear of being discovered, as a branch cracked or a leaf rustled, I pushed back into the bushes. It was long before I grew bolder, and dared to move freely. My only idea for the moment was to get away from these foul beings, and I scarcely noticed that I had emerged upon a faint pathway amidst the trees. Then suddenly traversing a little glade, I saw with an unpleasant start two clumsy legs among the trees, walking with noiseless footsteps parallel with my course, and perhaps thirty yards away from me. The head and upper part of the body were hidden by a tangle of creeper. I stopped abruptly, hoping the creature did not see me. The feet stopped as I did. So nervous was I that I controlled an impulse to headlong flight with the utmost difficulty. Then looking hard, I distinguished through the interlacing network the head and body of the brute I had seen drinking. He moved his head. There was an emerald flash in his eyes as he glanced at me from the shadow of the trees, a half-luminous colour that vanished as he turned his head again. He was motionless for a moment, and then with a noiseless tread began running through the green confusion. In another moment he had vanished behind some bushes. I could not see him, but I felt that he had stopped and was watching me again.

“I beg your pardon, Dr. Lanyon,” he replied civilly enough. “What you say is very well founded; and my impatience has shown its heels to my politeness. I come here at the instance of your colleague, Dr. Henry Jekyll, on a piece of business of some moment; and I understood...” He paused and put his hand to his throat, and I could see, in spite of his collected manner, that he was wrestling against the approaches of the hysteria — “I understood, a drawer...”

But here I took pity on my visitor’s suspense, and some perhaps on my own growing curiosity.

“There it is, sir,” said I, pointing to the drawer, where it lay on the floor behind a table and still covered with the sheet.

He sprang to it, and then paused, and laid his hand upon his heart: I could hear his teeth grate with the convulsive action of his jaws; and his face was so ghastly to see that I grew alarmed both for his life and reason.

“Compose yourself,” said I.

He turned a dreadful smile to me, and as if with the decision of despair, plucked away the sheet. At sight of the contents, he uttered one loud sob of such immense relief that I sat petrified. And the next moment, in a voice that was already fairly well under control, “Have you a graduated glass?” he asked.

I rose from my place with something of an effort and gave him what he asked.

He thanked me with a smiling nod, measured out a few minims of the red tincture and added one of the powders. The mixture, which was at first of a reddish hue, began, in proportion as the crystals melted, to brighten in colour, to effervesce audibly, and to throw off small fumes of vapour. Suddenly and at the same moment, the ebullition ceased and the compound changed to a dark purple, which faded again more slowly to a watery green. My visitor, who had watched these metamorphoses with a keen eye, smiled, set down the glass upon the table, and then turned and looked upon me with an air of scrutiny.

“And now,” said he, “to settle what remains. Will you be wise? will you be guided? will you suffer me to take this glass in my hand and to go forth from your house without further parley? or has the greed of curiosity too much command of you? Think before you answer, for it shall be done as you decide. As you decide, you shall be left as you were before, and neither richer nor wiser, unless the sense of service rendered to a man in mortal distress may be counted as a kind of riches of the soul. Or, if you shall so prefer to choose, a new province of knowledge and new avenues to fame and power shall be laid open to you, here, in this room, upon the instant; and your sight shall be blasted by a prodigy to stagger the unbelief of Satan.”

“Sir,” said I, affecting a coolness that I was far from truly possessing,” you speak enigmas, and you will perhaps not wonder that I hear you with no very strong impression of belief. But I have gone too far in the way of inexplicable services to pause before I see the end.”
